Cowden syndrome is an inherited condition that is characterized primarily by multiple, noncancerous growths (called hamartomas) on various parts of the body. People with the syndrome usually have large head (macrocephaly), benign tumors of the hair follicle (trichilemmomas), and white papules with a smooth surface in the mouth (papillomatous papules), starting by the late 20s. It is considered part of the PTEN Hamartoma Tumor Syndrome spectrum which also includes syndrome/resources/1" target="_blank">Bannayan-Riley-Ruvalcaba syndrome and syndrome/resources/1" target="_blank">Proteus syndrome. People who have Cowden syndrome are at an increased risk of developing certain types of cancer, such as breast, thyroid, and endometrial (lining of the uterus) cancer. Most cases are caused by mutations in the PTEN gene and are inherited in an autosomal dominant manner.[8504] Management typically includes screening for associated tumors and/or prophylactic surgeries.
